Farm ministers from 30 countries met at the UN Food and Agriculture Organization (FAO) for their second meeting after an initial one last year.
"Prices are expected to remain volatile over the next years," FAO chief Jose Graziano Silva said.
He said prices had eased from last year, adding that grain production had rebounded and higher stock-to-use ratios should bring greater stability.
"International prices have declined but they are still above their historical levels," he said.

He said FAO members should take advantage of the relative calm and prepare for future market turbulence to address food price volatility.
"If higher and volatile prices are here to stay, then we need to adapt to this new pattern," he said, pointing to the role played by better global governance in reducing food price spikes.
FAO said the Agricultural Market Information System (AMIS) created by the G20 in 2011 had proved "an effective new weapon in the arsenal".
